JLLN030 - 30Amp Fuse

JLLN030 - 30Amp Fuse

When selecting the right fuse for your needs, it’s not just about spotting a "30A" on the label. The Littelfuse JLLN030 is a Class T industrial cartridge fuse that brings together a solid 30-amp continuous current rating, fast-acting performance, and a smart current-limiting design. For maintenance teams, electricians, and equipment owners, understanding these precise ratings can make all the difference, eliminating the guesswork often involved in choosing the right Class T fuse. It helps ensure your equipment runs smoothly and safely!

Key Features and Benefits

• 30A continuous current rating — A clearly defined amperage makes it easier to match the fuse to equipment requirements.
• Class T configuration — Intended for equipment designed to accept the specified Class T fuse format.
• Fast-acting (F) — The manufacturer identifies the JLLN030 with a fast-acting opening characteristic.
• Current-limiting design — Provides the current-limiting family characteristic specified for the JLLN series.
• 300VAC maximum voltage — Supports compatible AC applications within its stated electrical ratings.
• 160VDC maximum voltage — Provides a separately defined rating for compatible DC applications.
• Non-indicating — The JLLN030 is specified without an indication feature.

Material Compliance and Certifications

The manufacturer information supplied for the JLLN030 does not specify UL, CSA, CE, RoHS, REACH, or other certification or material-compliance details. This should not be interpreted as meaning the fuse lacks a particular certification. If a listing, approval, or material requirement matters for the application, verify it in the markings and authoritative documentation for the exact JLLN030 catalog number.

Where It Works Best

The Littelfuse JLLN030 30A Class T fuse is best considered for compatible electrical equipment that specifically requires a 30-amp, fast-acting, current-limiting Class T industrial cartridge fuse. For an AC application, the relevant limits are 300VAC maximum with a 200 kA interrupting rating at 300VAC. For DC equipment, the corresponding specifications are 160VDC maximum and 50 kA interrupting capacity at 160VDC.
